• Cloud Interoperability is key for Hybrid Cloud
• Cloud strategy derives mainly from Cloud Management layer
• Cloud Management Layer : deploy, connect and manage user workloads
• iPaaS helps to integrate and connect application across multiple clouds
• Telco (SDN/NFV) has specific requirements/challenges connecting
multiple clouds
• iPaaS & Serverless can provide an architecture for Telco Cloud

3. Story of iPaaS

What is PaaS ?

What is iPaaS?
Market Definition/Description (based Gartner Report)
An integration platform as a service (iPaaS) provides capabilities to enable
subscribers (aka "tenants") to implement data, application, API and process
integration projects spanning cloud-resident and on-premises endpoints.
This is achieved by developing, deploying, executing, managing and monitoring
"integration flows" (aka "integration interfaces") — that is, integration applications
bridging between multiple endpoints so that they can work together.
“Enterprise iPaaS” (as per Gartner Definition)
If iPaaS is designed:
to support enterprise-class integration projects (that is, projects requiring high availability, disaster
recovery, security, service-level agreements [SLAs] and technical support from the provider)

iPaaS to play a key role in cross clouds.

PaaS v. iPaaS v. SaaS
refers to one cloud based
toolset that enables
developers to govern
services.
PaaS focuses on one
portion of a development
project, rather than an
entire infrastructure
integration PaaS
combines several
platforms, utilizing the
same benefits as PaaS at
a broader scale
Also creates unique set
of services across
multiple cloud residents
software as a service
(SaaS) uses a third
party provider to host
applications over
the internet
PaaS iPaaS SaaS
iPaaS vendors not only work toward integrating enterprise systems within the cloud, but also between
public and private clouds, all while keeping costs in mind

3. Story of iPaaS

• Adapters/Connectors are already created and always up-to- date.
• Reliable infrastructure.
• Citizen integrators can connect any software and create pipelines
• Manage all points of integration in one place.
• Visualization of all data streams in one place.

Interoperability
Testing Initiative /
standards
• Embracing Cloud
Technologies for
seamless service
deployments.
• Vendor lock-in.

Service Chain?
Network service chaining is a capability that
uses SDN to create a chain of network
services like firewalls, network address
translation [NAT], routing, Encryption, QoS,
Bandwidth, intrusion protection, edge
router, etc. in a virtual chain to automate
network connections to handle traffic flows
for in network connections.
Example : Video or VOIP session
Along with SDN and NFV together can use
the best available network resources and
help negotiate around network congestion
issues – all in an automated fashion.
•Why Service Chain:
•Construct a chain often built to support multiple applications, data sometimes passed
through unnecessary network devices or servers and consumed extra bandwidth and CPU
cycles.
•Not over provisioning as well as to meet future demands, a dynamic provisioning model
within a VLAN, VXLAN or across those boundaries without a third party provider.
Organizations working on these standards: The Internet Engineering Task Force (IETF), European Telecommunications Standards
Institute (ETSI) and Open Networking Foundation(ONF) - OpenFlow

Scenarios

iPaaS in Serverless Architecture : Exploring better interop and performance
This architecture provides : Seamless interop with iPaaS and Optimization with Serverless
3 Technologies working together:
Stage 1: iPaaS : Connector based interop
Stage 2: Serverless: Runtime gets them as events
Stage 3: PaaS: Gets it deployed in containers

A2A Market research prediction shows that iPaaS market will grow from USD 528 million in
the year 2016 to around USD 3 billion by 2021 with Compound Annual growth rate of 41.5%.
Intelligent PaaS : Making predictive scheduling, resource managements and
events. Integration of this kind of intelligence with iPaaS. (Intelligent iPaaS)
ML/AI: Machine Learning and Artificial Intelligence can make the cross
cloud deployment, management and maintenance more adaptive , self healing
and self optimizing
Changing IaaS Technologies: Distributed computing hardware modules and
its granularity and impose specific requirements to cloud technologies.
Adapting these to exploit the best of the hardware.
